Annotated Information
Function
LAX PANICLE (LAX) is involved in the formation of all types of axillary meristems throughout the ontogeny of a rice plant. Ectopic LAX expression in rice caused pleiotropic effects, including dwarfing, an altered pattern of stem elongation, darker color, bending of the lamina joint, absence of the midribs of leaves, and severe sterility.
Mutation
In strong mutant alleles of the LAX locus, such as lax-2 and lax-3, the initiation of lateral spikelets is completely suppressed, and panicle branches are also severely reduced. On the other hand, the defects were observed only in the lateral spikelets in lax-1, lax-4, and lax-5, which are weak mutant alleles of LAX. An insertion of a retro transposon was detected in the lax-1 allele(as showed in fig1). The existence of a long deletion, which contains five predicted genes, PG1 to PG5, was identified in the lax-2 allele. A 59-bp region was deleted in lax-3. Amino acid substitutions were found in lax-4 and lax-5, R50D or A49T, respectively.
Expression
LAX cDNA is 1,080-bp in length cloned by screening a cDNA library prepared from very young inflorescences. Sequencing of the LAX cDNA revealed that the LAX gene is intronless and encodes an ORF of 215 aa. It encodes a basic helix–loop–helix transcription factor and is expressed in the boundary between the shoot apical meristem and the region of new meristem formation. This pattern of LAX expression was repeatedly observed in every axillary meristem(as showed in fig2).
